The auction text never once mentions the Winter Classic but it does say the product is officially-licensed and made by Reebok. The design also matches that of a t-shirt that was leaked after the originally-scheduled 2013 game should have happened.

Even ignoring the general trustworthiness (or lack thereof) of eBay, I don't think this is what the Wings will wear on January 1, 2014.

Yes, the design matches that of the t-shirt found in January. I think it matches too well. We've already heard that the Maple Leafs will be wearing blue for the event. The Red Wings are expected to wear "vintage white" with red trim. I said when the t-shirts were found that I think that the Wings' shirt was red because no one would buy a dirty-looking t-shirt. To me, this looks like it was based on the t-shirt design, while official merchandise would have been done in the opposite order.
